[Surgical treatment for secondary pneumothorax in elderly patients].

Surgical treatment for secondary pneumothorax in elderly patients is very difficult because of having a high perioperative risk related to the presence of underlying chronic lung disease. In this study, we performed a retrospective review of elderly (> or = 70 years old) 35 patients with secondary pneumothorax who underwent surgical treatment between 2000 and 2009. Of the 35 patients, 31 were men and 4 were women with an average age 77.9 years old. Seventeen patients of them had already received oxygen therapy. They were not only in chronic respiratory failure but also malnutrition. Hospital mortality rate was 14.3%. Three patients died within 30 postoperative days and 2 patients were with hospital death after operation. The 5-year survival rate in patients with secondary pneumothorax was 41.7%. Although secondary pneumothorax is one of benign pulmonary diseases, its prognosis in elderly patients is poor. In conclusion, prompt diagnosis and treatment of secondary pneumothorax in elderly patients are mandatory. They could improve the outcome of this disease.
